What is missing for tablets in the APK?

Question

Android

Updated app to support tablets. Cleaned up the icons, added permissions for using high resolutions to the manifest. On the test tablet, everything works with a bang. BUT! After downloading the APK, I get a warning in the developer console: the APK file must contain retractable elements for all common tablet screen resolution formats. To expand your audience, optimize your tablet app. Then it will be added to the corresponding tab in the Play Store.

In principle, there are no menus in the application, purely navigation and several screens. Screenshots added, but even there I get a warning. What do they want from me?
